I don't know. I just have a Tamiya Mid-Pro hanging around in the garage unbuilt. The numbers would be easy enough, the only trick would be the single, underlined, "PINK LIGHTNING" insignia on the superstructure next to the driver's vision port. Some s SS 102 vehicles had this insignia on the rear hull where the jack block would normally be.
I don't know if Willy had this on the rear end or not, but he would have had it on the front.
